RICHARD EDWARD LEAGH, 0F COBALT, ONTARIO, CANADA.

LATCH MECHANISM FOR SPLIT STOCKS AND DIES.

To all whom it may concern:

Be it known that I, RICHARD EDWARD LEACH, of the town of Cobalt, in theProvince of Ontario, in the Dominion of Canada, have invented certainnew and useful Imgrovements in Latch Mechanism for Split tocks and Dies;and I do hereby declare that the following is a full, clear, and exactdescription of the same.

The invention relates to improvements in latch mechanism for splitstocks and dies, as described in the present specification andillustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel arrangement andconstruction of parts whereby the device is split centrally and securelylocked and held in proper alinement in its closed position.

The objects of the invention are to provide in such devices a machinewhich may be quickly handled in applying and removing from the work andto furnish an arrangement of parts in which durability and simplicityare assured.

In the drawings, Figure l is a perspective view of the device in itsclosed position.

. Fig. 2 is a perspective view of the device in its open position. Fig.3 is a vertical sectional view through the fastening device.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 and 2 are the halves forming the stock,said halves being hinged at 3.

4 is a central hole through the halves l and 2.

5 are channels in the wall of the central hole 1.

6 are recesses in the faces of the halves 1 and 2.

7 and 8 are the halves in the die fitted into the recess 6 and extendingthrough the hole 4: having the longitudinal channels 9 registering withthe channels 5 so that the cut tings by said die may pass out.

10 are the face plates also formed in halves and securely fastened tothe faces of the halves 1 and 2, said face plates having central holes11 through which the pipe or rod to be operated on extends through.

12 is a lug projecting beyond the half piece 2 at the open end andadapted to fit into the slot 13 in the half 1 bringing the parts 1 and 2in perfect alinement.

Specification of Letters Patent.

Application filed October 11, 1909.

Patented May 17, 1910.

Serial No. 522,054.

14 is a recess in the wall of the half 2 immediately below the lug l2.

15 is a recess extending vertically through the upper side of the recess14; and terminat ing adjacent to the top surface of the half piece 2.

16 is a pin having a threaded upper end and extending through a suitablehole into the recess 15, said pin having a latch member 17 at the innerend thereof, either forming part therewith or securely attached thereto,said latch member having the beveled surface 18 on its outer side.

19 is the head of the pin with a correspondingly threaded orifice andscrewed on to the top of said pin.

20 is the catch of the latch member extending outwardly from the halfpiece 1 immediately below the slot 13 and formed with the upwardlyextending end 21 having a curved or beveled outer surface over which thebevel surface 18 of latch member 17 may slip in closing the pieces 1 and2.

In the use of this device, the halves of the stock are closed over theend of the pipe, the latch member 17 slipping over the catch 20 andlocking the said pieces together, the lug 12 entering the slot 13 sothat the said halves are in perfect alinement. As soon as the threadingof the pipe or rod has been done, the latch member 17 is lifted bypulling on the head 19, thus raising said latch member so that it willclear the catch 20. During this operation, the cuttings from the pipe orrod have found their way out through the channels 5 and 9. When thehalves are opened, anything remaining can be readily shaken out and thestock and die thoroughly cleaned.

What I claim as my invention is:

In a device of the class described, a split die stock having in onesection thereof an alining slot out of the top and meeting edge facesand a lug projecting outwardly from the meeting face immediately belowsaid slot, said lug having an upwardly turned outer end, the othersection of said stock having an alining lug projecting from its meetingface adapted to fit into said alining slot, and a recess into saidmeeting face below said alining lug and extending upwardly in saidsection to the rear of said alining lug, said lug with the upwardlyturned end extending into said slot in the closed position of the stock,a pin extending through a corresponding hole in the top Wall of a stocksection and leading into said recess t0 the the upper Wall of therecess.

rear of said alining lug and having at the Signed at the town of Cobaltin the dislower end thereof an enlarged portion with trict of Nipissingin the Province of Ontario a beveled outer face forming a latch memthissixth day of October 1909.
